[Bug c++/21057] New: iso C99 complex double: problems with g++

["hartmann at physik dot uni-kl dot de" <gcc-bugzilla at gcc dot gnu dot org>]

Hallo.
I want to use the ISO C99 complex datatypes in c++ because they are faster than
the template complex types from std++.

g++ fails to work with ISO C99 complex in the following way:

typedefs+built-in-functions(conj)+unary minus are not working well together.

>>>>cat test.cpp
#include </usr/include/complex.h>

typedef complex double zcomplex;

int main()
{
  zcomplex f=1+_Complex_I*1;

  f=-_Complex_I;

  f=conj(f);

  return 0;
}

>>>>g++ -Wall test.cpp
test.cpp: In function `int main()':
test.cpp:9: error: wrong type argument to unary minus
test.cpp:11: error: wrong type argument to conjugation

>>>>g++ -v
